Crystal growth of LiGd1−xLuxF4 solid solutions by zone melting technique

► Stoichiometric mixtures of LiF−(Gd1−xLux)F3 were submitted to one Zone Melting cycle. ► Crystal growth of LiGd1−xLuxF4 solid solutions were obtained in part of the ingots. ► Ingots were characterized by SEM, EDS and X-ray powder diffraction. ► Transparent regions of the bars were proportionally to the initial Lu concentration.
